I have SpamSieve3 on an iMac running Sonoma 14.0. I read through all the upgrade instructions to get it working in Sonoma. However, every day it just stops filtering mail. I think maybe it has something to do with my screen saver or energy settings. Any suggestions for things I can check. I get SpamSieve3 working again by disabling it, then re-enabling it and hitting the “Uninstall Plug-In” (even though I did that at initial setup).
Most likely this is due to a macOS bug, not the screensaver or plug-in. The easiest workaround is to update to SpamSieve 3.0.1b2.
